<title>drm/display/dp_mst: Handle old/new payload states in drm_dp_remove_payload()</title>

<id>e761cc20946a0094df71cb31a565a6a0d03bd8be</id>
<content type='text'>
Atm, drm_dp_remove_payload() uses the same payload state to both get the
vc_start_slot required for the payload removal DPCD message and to
deduct time_slots from vc_start_slot of all payloads after the one being
removed.

The above isn't always correct, as vc_start_slot must be the up-to-date
version contained in the new payload state, but time_slots must be the
one used when the payload was previously added, contained in the old
payload state. The new payload's time_slots can change vs. the old one
if the current atomic commit changes the corresponding mode.

This patch let's drivers pass the old and new payload states to
drm_dp_remove_payload(), but keeps these the same for now in all drivers
not to change the behavior. A follow-up i915 patch will pass in that
driver the correct old and new states to the function.

<id>54618888d1ea7a26f8bccfb89e3c2420350c8047</id>
<content type='text'>
[why]
dc_link contains over 30k line of code, the decision is to break it
down to files residing in link folder based on functionality. This
change is the last break down change which will remove dc_link.c
file after everything is broken down.

[how]
Move remaining dc_link.c functions into link_detection, link_dpms,
link_validation, link_resource, and link_fpga and remove dc_link.
